In an interview with The Associated Press, Mohammad Javad Zarif said that fragments recovered from a missile fired by Houthi rebels into Saudi Arabia last year bore markings of the Standard Institute of Iran — not Iran's military industry.

"It’s a sign of quality," Zarif told the AP. "When people want to buy it, they look at whether it’s been tested by the Standard Institute of Iran that your cheese puffs are good, your cheese puffs will not give you a stomach ache."

"I mean, nobody will put the logo of the Standard Institute of Iran on a piece of missile," he added.

"I’m not saying Ambassador Haley is fabricating, but somebody is fabricating the evidence she is showing," he said.

The U.S. has accused Iran of supplying weapons to Houthi rebels in Yemen, including ballistic missiles.

In a news conference in December, Haley presented what she called "undeniable" evidence that Iran had manufactured missiles fired into Saudi Arabia, including debris from a short-range ballistic missile, an antitank guided missile, an unmanned aerial vehicle and exploding boat technology that have markings and features indicating origins in Iran.

The evidence that Haley presented was turned over to the U.S. by Saudi Arabia and the United Arabi Emirates — both regional opponents of Iran.
